Overview

We’re looking for a savvy front-end engineer to join our passionate Front-End Architecture team as a Senior Software Engineer II to help us scale and evolve Seismic’s front-end platform with a keen eye towards software quality, developer experience, and operational excellence. As a tech “unicorn”, this is an amazing opportunity for the right person to play a major role in shaping the front-end architecture and infrastructure of this pre-IPO software company, as we broaden our lead in the sales enablement space!

You will work closely with our product leads, engineering leads, designers, and the other members of the Front-End Architecture team to evolve and maintain Seismic’s Mantle component library, establish front-end standards, and build the shared infrastructure that powers a consistent, accessible, and performant user experience across the platform for the next ten years.

Who You Are:

• Seen as a major contributor in the team problem-solving process – you aren't afraid to share your opinions in a low-ego manner or roll up your sleeves and write critical-path front-end code, take on the refactoring of a significant shared component or architectural pattern.
• Deep experience across multiple software projects, driving the end-to-end development lifecycle of architecturally complex UI systems, component libraries, or design system implementations.
• Ability to think tactically as well as strategically, respecting what came before you and always thinking longer-term.
• Highly focused on operational excellence and software quality, with experience in front-end CI/CD pipelines, build tooling, and best practices for testing and deploying shared UI libraries.
• Your technical skills are sought after as you develop in a pragmatic and efficient manner.
• You enjoy solving challenging problems, all while having a blast with equally passionate and talented team members.

Who you are:

• BS or MS in Computer Science, a related technical field, or equivalent practical experience.

• Minimum of 8 years of Software Development experience within a SaaS business.
• Expert-level proficiency in HTML, CSS, and JavaScript, with deep experience building production applications in React and TypeScript.
• Strong proven record with user interface, interaction, and accessibility (WCAG) best practices, including hands-on experience auditing and remediating a11y issues.
• Expertise with designing and developing design systems and front-end component libraries (experience with or similar to the Mantle component library is a strong plus).
• Experience with designing for security (including Content Security Policy), performance optimization, internationalization/localization, and accessibility.
• Familiarity with modern front-end build tooling, CI/CD pipelines, and experience using LLM-powered development tools to enhance productivity and code quality.

What you'll be doing:

• Develop, improve, and maintain the Mantle component library, ensuring seamless integration and adoption across the Seismic platform.
• Diagnose and resolve complex front-end issues including Content Security Policy (CSP) violations, accessibility (a11y) defects, cross-browser rendering problems, and performance regressions to ensure reliability and maintain user trust.
• Leverage LLM-powered tooling and AI-assisted workflows to accelerate front-end development, improve code quality, and explore innovative approaches to UI generation and component authoring.
• Be a major player on the Front-End Architecture team, driving technical and architectural decisions for shared UI infrastructure and collaborating across multiple remote teams.
• Collaborate with globally-dispersed product managers, designers, and software engineers to define, build, and ship front-end components and patterns that create innovative solutions and add value to our customers' experience with Seismic.
• Explore emerging front-end technologies, web platform capabilities, and LLM-powered development tools, and bring your findings to life in our products and developer workflows.
• Participate in and contribute towards code reviews, bug/issue triage, and documentation.
• Contribute to troubleshooting CSP configurations, accessibility compliance, performance bottlenecks, and continuous quality improvements across the front-end platform.
